Abstract
A square baler has a pick-up device, a feeding channel, a baling chamber with a baling ram, side walls of the baling chamber, a hydraulic adjustment device to change the position of at least one pivotal side wall and corresponding sensors and control devices, which regulate the side walls. A control device regulates the baling force of the square baler. A pressure sensor measures the baling pressure in the hydraulic adjustment device. The baling pressure is then compared with a set pressure value. The difference in the value of the pressures is processed via a PID controller, which sends an adjustment signal to a hydraulic valve for adjusting the difference in the actual and set pressures.
